Impact separation type pedal

Abstract

The present disclosure provides a pedal 1 that includes a left bracket and right bracket that are combined such that a portion coupled to a hinge of a pedal arm and another portion fixed to a vehicle body are fitted to each other in an X-shape. A cover bracket is welded to the left and right brackets and over the X-shaped portion. A fixing pin welded to the left and right brackets and at a cross-point of the X-shape. The pedal arm is separated due to deformation in an impact direction in an oblique collision as well as a front, offset, or small overlap collision of a vehicle. Thus, the pedal makes it possible to prevent a driver from being injured by the pedal.

In this disclosure, pedals mean a brake pedal, a clutch pedal, and an accelerator pedal.[0004]For example, the pedal anti-pushing structure is rotated backward in a backward rotation type pedal when being pushed backward or prevents the pedals from being pushed in a pedal stopper type pedal when a vehicle is in an offset collision or a small overla...

AI Technical Summary

Benefits of technology

[0018]According to the impact separation type pedal for a vehicle of the present disclosure, the pedal is separated by a larger deformation of the dash panel than of a cowl fixing portion in a collision. The pedal can thus be separated even under various collision conditions particularly such as front / offset or small overlap collisions and oblique collisions. The disclosed pedal does not injure a driver and also provides the following effects.

[0019]First, reduction of the manufacturing cost is achieved because the pedal has a simple structure as compared with existing pedal stopper technology or backward rotation technology. Second, improvement of collision performance is achieved because the pedal hinge for separating the pedal is definitely separated even in any collision conditions. Third, improvement of strength is achieved because the pedal member rigidity-securing distance is decreased, as compared with the related art. Thus, the disclosed pedal is very advantageous in terms of strength and rigidity. Strength and rigidity are improved by adding a separation wall rib using a cross-coupling member applied to the hinge portion of the pedal. Fourth, improved operability of the pedal is achieved because a pedal stroke by spherical contact is made that provides smooth operation of the pedal by applying a ball to the structure for separating the pedal at the hinge portion in a collision. Fifth, improvement of the commercial value of the pedal is achieved because the disclosed pedal satisfies oblique collision regulations that are severe collision conditions.

Problems solved by technology

However, the anti-pedal pushing structure of the backward rotation type or the pedal stopper type secure only safety in an offset collision or a small overlap collision, but do not secure safety in an oblique collision under NHTSA.

When the pedal diagonally collides, the backward rotation lever cannot be rotated, so it is difficult to rotate backward.

The stopper at the cowl crossbar does not have enough rigidity to resist a pedal pushed in an oblique collision of a vehicle.

The pedal stopper has to have substantial strength, which necessarily increases the manufacturing cost and weight.

It is thus difficult to deal with this type of collision even with the most common pedal stopper.
